What is a Wave?


  • a wave transports energy
  • energy is transported in a wave through the disturbance of the particles in the medium

Do you realise that in a stadium wave, each person merely stands up and down but they do NOT move with the wave?
Yet the wave is said to be "moving" from corner of the stadium to another!

Try making a wave yourself. Observe that the particles do not move with the wave!
